Leupold Mark 4 35mm Medium Aluminum Scope Ring - FDE LU185236

The Leupold Mark 4 35mm Medium Aluminum Rings are a professional-grade mounting solution specifically engineered to eliminate the most common point of failure in a long-range rifle system: zero shift. While standard rings can deform or slip under heavy recoil, the Mark 4 series utilizes a rigid cross-slot interface and high-strength materials to ensure your optic stays locked in place. Finished in a durable Flat Dark Earth (FDE), these rings provide a rock-solid foundation for 35mm maintubes, ensuring that your point of aim remains your point of impact, shot after shot.

The technical edge of these rings comes from the use of 7075-T6 aircraft-grade aluminum. Unlike common 6061 aluminum, 7075-T6 offers significantly higher tensile strength and superior thread durability. This material choice is critical because the constant vibration of recoil and thermal expansion can create microscopic movements at the mounting interface. By utilizing a harder, more resilient alloy, Leupold ensures better torque retention and a stable optic-to-bore relationship, even when you are dialing your elevation turret to its mechanical limits for extreme-distance shots.

Despite their heavy-duty performance, these rings weigh in at just 3.4 oz per pair, providing high-performance rigidity without adding unnecessary bulk to your build. The precision-machined Picatinny cross-slot design provides a repeatable, "set-it-and-forget-it" clamping force that stands up to both environmental stress and high-kinetic impact. Proudly Made in the USA, the Mark 4 aluminum rings are the industry standard for shooters who demand a lightweight setup that never compromises on structural integrity.

Features

• 7075-T6 aluminum construction + higher tensile strength than 6061 = increased resistance to deformation and thread stripping
• Precision cross-slot interface + positive recoil lug engagement = zero shift mitigation under heavy recoil
• 35mm ring diameter + exact bore alignment tolerances = secure fit for large-tube optics without stress points
• Specified torque values (65 in-lbs clamp / 28 in-lbs top screws) + even load distribution = repeatable mounting and retained zero
